Duplicated call of onConnected() in Spring

[renjithraj2005]

I'm trying to set up a Socket.IO server with Spring boot, which also serves as an API for my application. I have a React frontend that consumes socket

The problem is when I call my service to connect, it calls the onConnected method of my Spring back twice. I tried to simplify it by removing, for example, the call to the client.joinRoom(sessionCode) method but the logs remain the same.

Yes, I had this same issue. In Java, addConnectListener is called twice when client connects to the server.

Update:
Seems It is fixed in 2.0.12.
